Could my symptoms indicate H. pylori bacteria infection?

One should get medical help as soon as possible. Your symptoms indicate the possible complication of your case due to hemorrhoids, for example blood clot. As for me, I would advise turning to a gastroenterologist or proctologist immediately in order to receive the right diagnosis and treatment.

Pain and blood in your stool can be a serious thing. Trouble in passing stool plus sourness are also not exempt. For example, hemorrhoids could be the cause although there are other causes like infections or diseases of the intestine such as IBD. Seek medical attention promptly for appropriate care must be taken into account as far as this is concerned. 

Are you experiencing brown bleeding and pain in your belly area? Brown bleeding might be due to the stomach or to some place in the digestive system. The pain in the epigastric region you are having could be due to your stomach. Try eating small, frequent meals and avoid spicy or greasy foods. If the bleeding persists or the pain gets worse, it is recommended that you see a healthcare provider for further advice.

I think you might have a stomach upset. When you take birth control pills with L Thyroxin, you might experience diarrhea. This could mean that the combo is affecting your gut. Keep yourself hydrated and consider taking the drugs at different times during the day. If it doesn’t stop, talk to a doctor so they can advise accordingly. 

Abdominal pain after eating may be caused by the swelling of your intestines, which is a common symptom of Crohn's disease. You may ask your doctor to let you try a different drug that might work better for your condition. The right medication that is most effective for you and is helping with your symptoms should be found out soon. Therefore, you should not forget to tell your doctor about the other treatment possibilities.
